SPECIFICATION forming part of Letters Patent No. 726,673, dated April28, 1903. Application filed August 29,1902. Serial No. 121,504. (Nomodel.)

To aZZ whom it may concern.-

Beitknown thatI, WALTER GOETHE, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements inSawing-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to improvements in sawing-machines, and has for itsobject to provide a saw adapted to cut the necessary slits or groovesinvolved in the production of the forms of packing-boxes for bottlespatented to John O. Schoenthaler in the two several Letters Patentnumbered 276,289, issued April 24, 1883, and 305,533, issued October 14,1884.

While my invention has been designed by me for the specificpurposenamed,it willbe apparent to any one skilled in the art ofwoodworking machinery that it may be utilized tov equal advantage inmany other forms of wood working.

My invention has for its essential object, however, the production ofslotted, grooved, and notched strips or other sections of wood such asare described in the Letters Patent above referred to and displayed inthe drawings accompanying the said Letters Patent.

My invention consists in the construction and combination of parts,which will be hereinafter specifically described and which will be morereadily understood by reference to the accompanying drawings, in whichFigure 1 is a side view of a machine embodying my invention. Fig. 2 is atop View of the same. Fig. 3 is an enlarged perspective of. thetransverse bars and guide-heads used in my machine. Fig. 4 is'aperspective of the upper adjustable frame of my machine. Fig. 5 is alongitudinal vertical section of the tilting bed of my machine. Fig. 6is a detail of construction, showing the screw and-worm attachment ofthe upper adjustable frame of my machine.- Figs. 7 and Sare perspectiveviews of different forms of products of my machine. Fig. 9 is a frontView of one of the transverse shafts and the adjustable saws carried byit. Fig. 10 is a longitudinal cross-section of the clutch and itsattachments, whereby the feeding mechanism of bed 2 and formedby theuprights 5 and top cross-bar 6.

Power is communicated to the machine by means of the belt 7 and thepulley 8, which is mounted upon the shaft 9. At the outer extremity ofthe shaft 9 and at the end nearest which power is applied is mounted thepulley 10, which is connected by the belt 11 with the pulley 12, mountedon the shaft 13. The pulley 14 is also carried by the shaft 13 and isconnected by the belt 15 to the pulley 16 on the shaft 17.

. Circular saws 18 are adjustably mounted .npon the shafts 9 and 17bymeans of collars 19 and screws 20, as shown in Fig. 9. Guides 21 areprovided with slots 22, extending through the upper and-lower portionsof their vertical sides. The guides '2lare mounted upon the cross-bars23, as shown in Fig. 3, by means of a block 24, carried by the slot 25,and to which blocks 24 they are connected by means of the screw 26.Anynumber of these guides may be placed upon the cross-bars, theirnumber depending upon the thickness and length of the strips which areto be sawed. The bars 23 are mounted upon the endless chains 27, whichchains are carried by the sprockets 28 and 29. The depth of the bottomcuts in the strips operated upon is determined by the adjustment of thesprockets 28, which sprockets are carried by the adjustable blocks 31,which are adjustably mounted in the vertical slides 32 in the brackets33, and their adjustment is regulated by the screw 34.

At the extremity of the shaft 9 the pulley 35 is mounted, which pulleyis connected by the belt 36 with the pulley 37, mounted on the shaft 38,which shaft is provided witha clutch 39, actuated by the lever 40 andtrip 41. The shaft 38 is also provided with a gear 42, which intermesheswith the gear 43,

mounted on the shaft 44. The sprockets 29 are carried by the shaft 44and are caused to actuate the endless chains 27 by the operation of theclutch 39.

By means of the adjustable mounting of the circular saws 1S and theadjustment of the endless chains 27 any desired number of cuts or slotsat any desired interval and of any desired depth may be made in thelower edges of the strips of material operated upon.

The upright members 5 are provided with the frame 45, as shown in Fig.4. This frame is vertically adjusted by means of the screws 46, mountedupon the transverse member 47, which screws are actuated by the gears 48and the worms 49, mounted on the shaft 50, which shaft is actuated bythe crank 51.

The shaft 17 is pivotally connected to the shaft 13 by means of the bars52 and normally rests upon the lower transverse members 53 of the frame45. At each side of the frame 45 the shaft 17 is suspended by means oflinks 54. At one extremity the link 54 is engaged at the end of thelever 55, which is rigidly mounted upon the shaft 56. At the oppositeextremity of the shaft 56 the other link 54 is engaged with the arm 57,which is rigidly fastened to the end of the shaft 56.

The disengagement of the shaft 17 and the saws 18, carried thereby, iseffected by moving the shaft 17 to the desired position by means of thelever 55 and then inserting a pin through that one of the holes 5 in theupright 5 which is next beneath the lever 55.

By means of the operation of the lever 55 the shaft 17 and the sawscarried by it may be thrown into or out of engagement with the surfacesbeing sawed. As the material indi-' cated and used under the patents ofSchoenthaler, above referred to, is a thin strip or veneer, as shown inFigs. 7 and 8, which strips or veneer are very thin, light, andfrangible, it is desirable and necessary that the machine whereby theyare cut shall be provided with means for accurately cutting and holdingthem firmly at all points possible. To this end I have provided myadjustable frame 45 with a series of guide-racks 58, which arerectangular in form and adjustably mounted upon the transverse membersof the adjustable frame 45. These transverse members are preferablyformed, as shown in Fig. 4, of the angle-bars 59 and 60, the member 61,and the slot-ted member 62, containing the slot 63, arranged as shown.The guide-rack 58 is then provided with the adjusting-screw 64, by meansof which the rack is loosened from or attached to the transverse slottedmember 62, as may be desired. I also provide my sawing-machine with atilting bed 65, as shown in Fig. 5, which is hinged at its rearextremity by means of the pivots 66 and adjustable at the front by meansof the screws 67, mounted in the lugs 68.

The space between the lower saws is provided with the additional guides69, which are laterally adjustable in the shoulders 70, formed in thetilting bed 65, by means of the screws 71, extending through the slots72.

It will be seen that I have thus provided means for cutting the stripsor veneer of the aforesaid patents to Schoenthaler with any desireddepth and number of grooves, both at the top and bottom, and, further,that by means of the guides 21, mounted upon the endless chains 27, Ihave provided a cheap, effective, and practically automatic feedingmechanism whereby the strips or veneer may be fed to the machine andwhich feeding mechanism may be thrown into or out of opera tion asdesired by means of the trip 41 and its connections.

The operation of my machine is as follows: The guides 21 are adjustedupon the crossbars 28 in order to fix the distance between the cutswhich are to be made in the upper and lower edges of the strips whichare to be operated upon. The saws 18 are then ad justed so that as thematerial is fed toward them by the guides 21 the saws 18 upon the uppertransverse shaft will cut through the slots 22 and the strips carried bythe guides. The saws 18 upon the lower transverse shaft are adjusted tooperate through the slots 22 and to make a corresponding cut in thelower edge of the material as it is fed to the saws 18 by the forwardmovement of the guides 21. The operation of the belt 7 revolves thepulley 8 and its connections, including the sprockets 28 and 29 andendless chains 27. The chains 27 carry with them the guides 21 and thestrips which are being operated upon and which have been fed intoposition by the operator at the front of the machine above the sprocket28. The strips are fed vertically and are carried toward and between thesaws 18, so that the requisite cuts are formed in their upper and loweredges as are shown by the specimens of such figures, as shown in Figs. 7and 8. The strips when out are carried on toward the rear of the machineby the endless chains 27 and are discharged upon the floor or areceiving table as the guides 21 are carried over the sprockets 29.

In Fig. 11 there is shown an enlarged view of the front portion of amachine embodying my invention, showing the relationship between thesaws and the work and the carrier.

, I have indicated, by depicting the last position of the hand of theoperator as the ascending guide 21 (which I mark2l for the purpose ofdistinguishing it from the other members of the series of guides 21) iscarried to a vertical position around the sprocket 28, the manner inwhich the work is caught and held by the guides 21. It will be perceivedthat the next movement of the operator after the position of his handshown in Fig. 11 will be the withdrawal of the hand as the guide 21fassumes a vertical position and is brought into contact with the stripsand exerts a lateral holding pressure upon them, such as is shown to beexerted upon them by the hand in the position shown in the said figure.

While in Fig. 2 I have only shown two of the guides 21 upon each of thecross-bars 23.

and have shown a number of the circular saws 18, the particular numberof the saws 18 and guides 21 there shown is immaterial, as in practice Iintend that there shall be one of the guides 21 to correspond with eachone of the circular saws 18.

The guide-rack 58 is of the form shown in perspective in Fig. 4, and itslower surface serves as a guide to prevent the strips'of veneer whichare being operated upon from being thrust upwardly and out of alinementwith each other during the process of sawing.

Having thus described my invention, what I claim as new, and desiretohave secured to me by the grant of Letters Patent, is
